(Knowable Magazine) – Researchers are testing CAR T cell therapy as a way to reset the immune system in lupus, Graves’ disease and other conditions where the body’s defenses go rogue

Originally designed to target and wipe out cancer by reprogramming the patient’s immune cells, CAR T is now being offered to patients in hundreds of clinical trials for autoimmune conditions like multiple sclerosis, lupus, Graves’ disease, vasculitis and many others. The hope is that CAR T can duplicate the success it has demonstrated in a range of blood cancers by hunting down and eliminating cells that target the self in autoimmune diseases. This would essentially reset the body’s defenses to a state like the one that existed before the disease took hold.

But along with CAR T’s promise come risks, questions and challenges. There’s uncertainty about how well it will work for autoimmunity and how long any benefits might last, as well as what long-term side effects might arise. (Read More)
